All ISOtunes products come with a charging cable, allowing them to be recharged wherever you have access to a USB port, such as through a computer, wall outlet, or adapter. 

After plugging the USB end in to a USB port, locate the charging port on the battery module of your ISOtunes product, remove the safety flap, and insert the other end into the charging port. The light on your battery module will turn red to indicate the product is charging and it will turn blue when charging is complete. 

Please note, however: do NOT recharge your ISOtunes product using a "high power" or "fast" adapter or power source above 5V or 2 Amps. This may short-circuit the product and create a defect. 

ISOtunes microphones have been designed specifically to block out steady state background noise, thereby allowing for phone calls in many loud environments, such as with vacuums, engines, machines, or saws running in the background. 

However, ISOtunes microphones are not designed to eliminate impact noises, such as gun shots, so these will still come through loud and clear on calls and are likely to make conversations difficult. 

A general pointer for increasing call quality: please ensure the control module (which houses the microphone) is not tucked around the back of your head, but rather under your right ear or otherwise not blocked from access to your mouth.

Press and hold the power button until you see the indicator light on the control module flashing red and blue. This means your product is in pairing mode. 

A few things may be causing you to still hear outside noise when wearing ISOtunes hearing protection.

1. You purchased a product with Aware Technology™. Aware Technology™ purposefully amplifies outside noise, similar to a hearing aid, to improve your situational awareness and safety. You can turn Aware Technology™ off by locating the Aware Volume buttons and pressing “-” until you hear a beep.

2. You need a larger eartip size. ISOtunes TRILOGY™ eartips block noise with heat activated polyurethane foam. This foam needs to fully fill your ear canal to block the optimal amount of noise. The right size eartip should:
- feel snug but not painful
- easily stay in your ear
- block the greatest amount of noise 

3. You’re wearing silicone eartips. ISOtunes products come with double or triple flange silicone eartips for casual listening. These eartips should not be used to block noise in loud environments. Instead, use the provided ISOtunes TRILOGY™ foam eartips.

4. You’re experiencing noise-isolation, not noise-cancellation. All ISOtunes products use noise-isolation to passively block noise. At this time, ISOtunes does not sell any product with active noise-cancellation technology. 

Please go to our Product Support Page and select your product to be taken to a technical support page specifically for that product. 

Single Number Rating (SNR) is a method used to indicate the level of noise reduction provided by hearing protectors. The SNR is a single value that represents the average amount of noise reduction that the hearing protectors provide across a range of different frequencies. The SNR value is expressed in decibels (dB), and the higher the SNR value, the greater the amount of noise reduction provided by the hearing protectors. For example, if a pair of hearing protectors have an SNR of 30 dB, they would reduce the overall noise level by an average of 30 dB.

For hearing protection, ISOtunes in Europe are tested and approved in accordance with EN 352 specifications. Additionally, ISOtunes SafeMax Technology built into every product ensures a maximum volume output of 82 dB, an identified level of safe sound exposure throughout a work day. As such, all ISOtunes products meet requirements to be used as hearing protectors in the workplace.

Beyond hearing protection, all ISOtunes products are tested to IEC standard 60529 for International Protection Markings, which rate the degree of protection provided by mechanical casings and electrical enclosures against intrusion, dust, accidental contact, and water.

All ISOtunes products are tested in EN 352 hearing protection standards and issued Single Number Ratings (SNRs) accordingly. Meeting both hearing protection and hearing conservation standards for a full day of use in the workplace. 

That said, each workplace may have its own specific rules and restrictions on what hearing protection devices can, cannot, or must be used to ensure prevention of hearing loss. For most facilities, the main requirement is that the Single Number Rating for the devices is sufficient.



If you're unsure, simply ask your manager or company’s Safety Official to determine whether or not ISOtunes products are suitable for your workplace. And when using ISOtunes products, please abide by the rules established by your place of employment. 



Contact us if you would like more information about getting ISOtunes approved for your workplace.

ISOtunes products do an excellent job of blocking outside noise. As such, they should NOT be used in environments where users need to be fully aware of their surroundings for personal safety reasons. For example, we do NOT recommend using them while driving a car or riding a motorcycle. Similarly, we do NOT recommend them for use when riding a bicycle outside. The user is solely responsible for ensuring that ISOtunes products are used ONLY in safe environments.

Yes. All products with Aware Technology™ have the ability to make phone calls using noise-isolating microphones.

It depends. Aware Technology™ amplifies outside noises through omni-directional microphones. If you are hearing static or white noise, Aware Technology™ is likely magnifying it from your surroundings. This is considered normal. As with most hearing aids or enhancers, it may take time for you to adjust to the enhanced sound. 

We suggest you test the product with the Aware Technology™ turned off. To do so, please locate the Aware buttons and press the “-” button until you hear a beep. If you still hear static noise, we consider this a product defect and you should contact our customer service team for support. 

ISOtunes products with Aware Technology™ and ISOtunes Sport products with Tactical Sound Control™ are both great for handling loud impulse noises. Although they look and operate very similarly, the sounds and environments they are built to handle are very unique. 

ISOtunes Sport products are intentionally built to protect firearm users from gunshot noise. ISOtunes products with Aware Technology™ are built to protect those who use tools and loud equipment from impulse noises (nail guns, hammers, etc.).

Aware Technology™ is great for communicating in sporadically loud environments. Noises like nail guns and hammers will be blocked by Awre Technology™, while safe environmental sounds will be amplified. Aware Technology™ is especially helpful in environments where enhanced situational awareness is necessary. 

Aware Technology™ is not well suited for consistently loud environments. When exposed to steady-state noise above 79dB, Aware Technology™ will passively block all outside sound, similar to a standard hearing protector. Aware Technology™ will not amplify outside noise until the steady state-noise ends or falls below 79dB.  In these cases, we recommend turning Aware Technology™ completely off until you’re done working in that environment.
